Timothy wroteNot sure but look close enough from Biglow & Dowse Co Hardware 1906 catalog Nos. 390 to 392.
Tim! That looks damned close! I would say it is probably the one, because I’ve not seen the exaggerated faux leather grain on others; and the hinge-pin and rivits are in the same place; and the proportions are the same. Even the border line, the way it arches around the lower rivit and upper hinge pin, seems the same.
It is not exact, but of course the image is an artist’s engraving, and in such cases I don’t think it is normal to expect every line (of grain in this case) to be exactly the same. Given that, though, I’d say this is the one.
I’ll search for another actual example, using your find, to see if the casting is the same.
Thanks so much for your time looking for and finding this. Proto.
